Full Review
The BHA toner has long been the castor oil of skincare — effective, respected, and about as enjoyable to use as a dental cleaning. Most 2% salicylic acid toners take a scorched-earth approach to exfoliation: strip the pores, dry the surface, and let the moisturizer handle the collateral damage. Anua looked at this dynamic and asked a genuinely interesting question — what if the toner itself did the repair work?
The result is a formula that reads like a peace treaty between exfoliation and hydration. Salicylic acid sits fourth in the INCI list at a full 2% — the maximum over-the-counter concentration — so this is not a toner that has been watered down to earn its 'gentle' descriptor. The gentleness comes from everything surrounding the BHA, not from diluting it. Ceramide NP with hydrogenated lecithin provides barrier-repair lipids. Eight forms of hyaluronic acid create a hydration safety net. Centella asiatica soothes the inflammation that exfoliation can trigger. Tea tree extract adds antibacterial coverage. It is an exfoliating toner wearing full protective gear.
The dual BHA strategy deserves attention. Alongside the pharmaceutical-grade salicylic acid, Anua includes Salix Alba (willow) bark extract — the natural precursor to salicylic acid. Willow bark converts to salicylic acid through enzymatic processes on the skin, providing a slower, gentler secondary exfoliation that extends the active's working time without increasing peak irritation. It is a subtle formulation choice that most users will never notice and that quietly contributes to the toner's reputation for being effective without being aggressive.
On the skin, this toner is refreshingly uncomplicated. Pump out a couple of doses — the packaging is functional and hygienic — and pat it onto clean, dry skin. The texture is watery with the slightest viscosity, and it absorbs within seconds. What follows is the main complaint that follows this product everywhere: tackiness. There is a film. It is not terrible, it is not permanent, and it largely disappears once you layer your next product over it, but it is there, and if you are the type who cannot tolerate anything less than a clean, matte finish between steps, it will bother you.
The scent is another divisive point. There is no added fragrance, but salicylic acid and tea tree extract have their own opinions about how they smell, and those opinions lean medicinal. Some users describe it as faintly reminiscent of burning rubber, which is both accurate and a testament to how subjective scent perception is. It dissipates quickly, but sensitive noses should be warned.
Results-wise, this toner delivers on its core promise. Within two weeks of consistent evening use, blackheads become less visible and the overall texture of the skin smooths out — that satisfying feeling of running your fingers across your cheek and finding less resistance. Pore congestion clears gradually rather than dramatically, which is consistent with a well-buffered 2% BHA approach. This is not the toner that will give you a dramatic before-and-after transformation overnight. It is the toner that will keep your pores consistently clear if you use it regularly.
Where it falls short is stubborn, deep-seated congestion. Users accustomed to the immediate dissolving power of more aggressive BHA products may find this too mild for their needs. The gentle formulation that makes it accessible to BHA beginners is the same quality that limits its ceiling for experienced exfoliant users with severe congestion. It is an excellent first BHA and an excellent maintenance BHA, but it may not be the BHA that conquers your worst breakout.
Anua launched this toner in late 2023 as the exfoliating counterpart to their enormously popular Heartleaf 77% Soothing Toner. It was clinically tested at the Korea Institute of Dermatological Sciences and quickly gained a following on TikTok, where it became shorthand for 'the BHA that doesn't hurt.' Over a thousand reviews later, the consensus is remarkably consistent: gentle, effective for mild to moderate congestion, slightly tacky.
At twenty dollars for 150ml, the value is solid. You are getting a premium-ingredient BHA toner with ceramide, multi-weight HA, centella, and tea tree — supporting ingredients that many competitors omit to keep costs down. The pump dispenser is a practical upgrade over the cotton-pad-and-splash bottles that dominate this category. Three to four months of nightly use from a single bottle makes the per-use cost negligible.
For the blackhead-prone user who has been punished by every BHA product they have tried, this toner represents something genuinely different: exfoliation that respects the skin it is working on. The tackiness and scent are real compromises, but they are the price of a formula that prioritizes your barrier alongside your pores.
Formula
Key Ingredients
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Salicylic Acid (BHA) (2%) | The primary exfoliant at the maximum OTC concentration, positioned fourth in the INCI list. Salicylic acid is oil-soluble, allowing it to penetrate into pores and dissolve the sebum plugs that cause blackheads and congestion. In this formula, it works alongside willow bark extract as a complementary natural BHA source for a dual exfoliation approach. | well-established |
| Melaleuca Alternifolia (Tea Tree) Extract | Provides anti-inflammatory and antibacterial support that complements the pore-clearing action of salicylic acid. Tea tree extract helps manage the bacterial component of acne while reducing redness around active breakouts — addressing both the clog and the inflammation simultaneously. | well-established |
| Salix Alba (Willow) Bark Extract | A natural source of salicin, which converts to salicylic acid on the skin. In this toner, willow bark acts as a secondary BHA source that extends the exfoliating activity with a gentler, slower-release mechanism alongside the pharmaceutical-grade salicylic acid. | promising |
| Centella Asiatica Extract | Provides soothing and wound-healing support that offsets the potential irritation from 2% salicylic acid. The centella extract helps maintain barrier integrity during the exfoliation process, reducing the redness and sensitivity that BHA products can provoke. | well-established |
| Ceramide NP | A skin-identical lipid delivered alongside hydrogenated lecithin for barrier repair. In an exfoliating toner that removes dead skin cells, ceramide NP helps replenish the barrier simultaneously — preventing the over-exfoliation cycle that many BHA products create. | well-established |
| 8 Types of Hyaluronic Acid | Eight molecular forms of hyaluronic acid provide hydration across multiple skin layers. In a BHA toner that can be drying, this multi-weight HA complex counteracts moisture loss by creating a gradient of hydration from deep to surface level. | well-established |

Science & Expert Perspective
The Science
Salicylic acid at 2% is the most extensively studied OTC concentration for acne and pore management. A 2015 review in Clinical, Cosmetic and Investigational Dermatology confirmed that 2% salicylic acid significantly reduces comedone count and inflammatory lesions compared to vehicle alone, with a favorable side effect profile. The oil-solubility of salicylic acid — unique among common hydroxy acids — allows it to penetrate the sebum-filled environment inside pores, dissolving the lipid matrix that holds comedonal plugs together.
The dual BHA approach in this toner combines pharmaceutical salicylic acid with Salix Alba (willow) bark extract. Willow bark contains salicin, which is enzymatically converted to salicylic acid through esterase activity on the skin surface. Research published in Phytotherapy Research has demonstrated that willow bark extracts provide anti-inflammatory and antimicrobial activity beyond what salicin alone would produce, suggesting additional phenolic compounds contribute to the overall effect.
Melaleuca alternifolia (tea tree) extract has well-documented antibacterial activity against Cutibacterium acnes. A landmark study published in the Medical Journal of Australia (1990) compared 5% tea tree oil to 5% benzoyl peroxide for acne treatment and found comparable efficacy in reducing inflamed and non-inflamed lesions, with fewer side effects. While this toner uses tea tree extract rather than concentrated oil, the antimicrobial contribution complements the pore-clearing action of salicylic acid.
The inclusion of ceramide NP with hydrogenated lecithin addresses a common limitation of BHA products — barrier compromise from repeated exfoliation. The lecithin-ceramide delivery system mimics the lipid architecture of the stratum corneum, potentially replenishing barrier lipids during the same step that removes dead cells. This dual-action approach aligns with research published in the Journal of Investigative Dermatology showing that ceramide-supplemented exfoliant formulations maintain lower transepidermal water loss (TEWL) values compared to conventional exfoliants.

Dermatologist Perspective
Dermatologists frequently recommend salicylic acid as a first-line topical treatment for comedonal acne and blackheads. Board-certified dermatologists note that 2% is the optimal OTC concentration — effective for mild to moderate acne while maintaining tolerability for most skin types. The addition of ceramide NP and hyaluronic acid in this toner reflects a clinically sound approach to exfoliation, as dermatologists increasingly emphasize that maintaining barrier integrity during active treatment improves both tolerance and long-term outcomes. This formulation is commonly recommended by dermatologists for patients who have experienced irritation with simpler BHA products, or as a maintenance treatment alongside prescription acne regimens.
Guidance
Usage Guide
How to Use
After cleansing and drying your face, pump 2-3 pumps of toner onto your palm or a cotton pad. Pat or swipe gently across the face, focusing on areas of congestion like the nose, chin, and forehead. Avoid the immediate eye area. Wait 1-2 minutes before applying your next skincare step. Start with 2-3 times per week and gradually increase to nightly use as tolerated. Use in the PM routine only. Always apply broad-spectrum sunscreen the following morning, as BHA increases photosensitivity.
Value Assessment
At $20 for 150ml, this toner offers competitive value in the BHA category. The supporting ingredient list — ceramide NP, eight hyaluronic acid forms, centella extract, tea tree extract, and vitamin E — goes well beyond what most BHA toners include at this price point. A single bottle provides 3-4 months of nightly use, bringing the per-use cost below $0.20. Only one size is available, so there is no bulk discount option. For an emerging brand, the clinical testing from the Korea Institute of Dermatological Sciences adds credibility that partially offsets the limited long-term track record.
Who Should Buy
Anyone with oily or combination skin struggling with blackheads, clogged pores, or mild acne who wants effective BHA exfoliation without the harsh stripping sensation. Particularly well-suited for BHA beginners and those who have found other salicylic acid products too irritating.
Who Should Skip
Those with dry or very sensitive skin who may not tolerate even gentle BHA exfoliation. Also not ideal for users dealing with severe or cystic acne who need prescription-strength treatment, or anyone who cannot tolerate the tacky finish and medicinal scent.

Myth vs. Reality
Myths & Misconceptions
Myth
BHA toners should sting to be effective — if you feel nothing, it's not working.
Reality
Stinging indicates irritation, not efficacy. The 2% salicylic acid in this toner works by dissolving oil-based plugs inside pores regardless of whether you feel a sensation. The lack of harsh sting is a feature of the gentle formulation, not a sign of weakness.
Myth
You need to wait 20-30 minutes after applying a BHA toner before layering other products.
Reality
While early acid toner advice recommended extended wait times, current dermatological consensus suggests 1-2 minutes is sufficient for the acid to begin working. The slightly acidic pH of subsequent products won't significantly neutralize the BHA.
FAQ
Frequently Asked Questions
Is the Anua BHA 2% Toner gentle enough for sensitive skin?
This toner is formulated to be gentler than many 2% BHA products thanks to its soothing centella asiatica, ceramide NP, and multi-weight hyaluronic acid complex. However, 2% salicylic acid is still an active exfoliant. Start with every other night and monitor for irritation — the formula supports sensitive skin better than most BHA toners, but individual tolerance varies.
Does the Anua BHA Toner actually work for blackheads?
Yes — the 2% salicylic acid is oil-soluble, meaning it penetrates into pores to dissolve sebum plugs that form blackheads. Users consistently report visible reduction in blackheads within 2-4 weeks of regular use. The added willow bark extract provides a secondary BHA source for sustained pore-clearing action.
Can I use the Anua BHA Toner with retinol?
Yes, but not on the same night. Alternate between the BHA toner and your retinol product to avoid over-exfoliation. On BHA nights, follow with a hydrating serum and moisturizer. The ceramide NP and hyaluronic acids in this toner help buffer the combined effects of both actives when used on alternating nights.
Why does the Anua BHA Toner leave a sticky feeling?
The slight tackiness comes from the hydrating ingredients — particularly the multi-weight hyaluronic acids and the botanical extracts. This film actually helps subsequent products absorb better. The tackiness diminishes significantly once you apply your next skincare step on top.
Is 2% BHA strong enough to clear acne?
2% is the maximum OTC concentration for salicylic acid and is effective for mild to moderate acne, blackheads, and pore congestion. For severe or cystic acne, a dermatologist-prescribed treatment may be needed. This toner works best as a preventive and maintenance tool for keeping pores clear.
How often should I use the Anua BHA 2% Toner?
Start with 2-3 times per week and gradually increase to nightly use as your skin builds tolerance. Most users settle at every-night or every-other-night application. Do not use it in the AM and PM — once daily in the PM routine is sufficient. Always follow with sunscreen the next morning.
Is the Anua BHA Toner safe during pregnancy?
Topical salicylic acid at 2% or less is generally considered safe during pregnancy according to ACOG guidelines. This toner falls within the safe range. However, Anua recommends patch testing during pregnancy due to hormonal skin changes. Consult your healthcare provider for personalized advice.
